METAL CAR-ROOF.

T0 aZZ whom it may concern:

Be it known that I, JAMES V; MOHLER, a citizen of theUnited States", and a resident of the city of Oelwein, county of Fayette, and State of Iowa, have invented certain new and useful Improvements in Metal Car-Roofs,of which the following is a specification. {I I My invention relates to improvements in metal car roofs and hasfor its object the production of a metal car roof which will be easily removable, durable in construction and economical in manufacture. A further object is the production of metal car roof formed: in sections and having a durable, economical, simple and water-proof method for joining the sections together. A further object is the production of a metal roof having an air chamber extending longitudinally thereof.

Other objects will appear'hereinafter.

The invention consists in, the combinations and arrangements of parts hereinafter described and claimed.

The inventionwill be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1, is a side elevation of a car embodying the invention,

The preferred form of construction,- as illustrated in the drawings, consists of a car 1 having a metal roof 2, comprising an outside roof and an inner roof, leaving an air chamber between the two said roofs.

' The inner roof is constructedof metallic sheets 8 secured at the ends by suitable fastening means l-to the lower'flange 5 of a channel iron 6, disposedtransversely between sheets 3, andthe "outer roof sheet 7 adjacent the carline8.

Theouter roof sheet 7,

of the device ferred to make of heavier material than'the inner roof sheet3, has an upwardly extending and inwardly bent flange 9 at both ends except at the ends of the car. .This sheet 7 Specification of Letters Patent. Application filed March 31,1919. Serial No.

ber of sections, as shown, thenumber of sec- 7 I tions depending upon the length of the sheets 8 and 7 or the distance between the carlines 8. These sheets 3 and 7, or the distance between the carlines 8 can be of any desired predetermined. length. -It (is thus seen that between theouter roof or the sheets 7, and the inner roof or' the sheets 3, there is a longitudinally extending air chamber 17. I Y j Extending transversely .of the roof of the car, superimposed on members 7, at the section lines of sheets 3 and 7, is an inverted channel member 12 having" downwardly projecting flang s" 13 adapted to engage the ends of the members 9, thereby serving as a binding member to firmly lock the ends of the members 7 in their disposed position. The member 12 is bent to conform to the periphery of the roof of the car andthereby servesas a cap in making a water-tight joint at, the-sections 'ofthe roof.

The members 3'and 7 are curved so as to make a bow shaped roof. The sides of the members 3 and 7, and the ends of the members 12 are bent so as tobe parallel to and in close engagement with the sides of the car with which used,as shown iniFig. 3. The sides of the members 3- and 7 and the ends of the members 12 are securely fastened to-the side of the car by bolts 14 passing throughv the ,Hcarline "or longitudinal'ly exte'nding beam 16 and the member 18. Cooperating with the bolts 14, on the inside of the car, are. nuts15 closely clamp ing themembers ,3, 7 and12f in position on the sides 'of1 .the car. Extending longitudinally through the length of the car is a Z-shaped or doubled angled member 18 disforming downwardly projecting flanges 35,.

tening means 22, on the inner surface and adjacent the upper edge of member'21, extending transversely of the roof, is an angle iron23, to thehorizontally extending web loaded as to materially raise the temperaof which is securely fastened, by suitable fastening means 24, the outer end of terminal member 8. The outer end of terminal member 7 embraces the top orthe base of the inverted U of member 21. The-end of said member 7 is flanged downwardly and is securely fastened in close engagement with the short leg of the U part of member 21 byrivets 26, or other suitable fastening means. v

Secured to the members 21and 7, by

rivets 26, is an angle iron 39 forming a bracket upon which is secured, by bolts 27 and nuts 28, the running boards 30 of the car, having a block 31 interposed between said bracket and said running boards. The bolts 27 are counter-sunk in said runnin boards, as clearly seen in Fig. 2, thereby af fording a clear and uninterrupted surface on said running boards.

The carlines8 are preferably constructed of metal, and are channel shaped and extend transversely of the car at the intersection lines or the ends of members 3 and 7. Bolts 82, having fixed collars 41, pass through the base 34 of the channel member 8, through the channel member 12 and into the block 40. Nuts 33, seated in grooves in said blocks 40, cooperate with said bolts 32 and serve to bind the members 8, 12 and 40 securely together. The base member 3a of member 8 is downwardly bent at'its ends,

which are securely fastened by bolts 14, as shown in Figs. 3, 42 3116]. 6.

Fig. 5 shows a modified form of construction of the carline 8'. In the modified form as shown in Fig. 5', the upper ends of the sides of the channel member 8' are outwardly inclined and securely fastened to the inwardly'bent edges of members 7 by rivets 36, the ends of the members 3 being also upwardly flanged and secured to the sides of member 8, at its base, by rivets .38. In, this modified form the member'8, as a whole, conforms to the shape of the periphery of the roof, whereas, in the form shown in Figs. 2, 3 and 6, only the upper edges of member 8 so conform. In the modified form used, the channel member 6 is also eliminated. 7

By the construction of a roof of the na ture described, it is readily apparent that an air chamber, extending longitudinally'of the car, is provided between an inner and an outer roof. As clearly seen in Figs. 2 and 5, the method of securing the ends of the members 7 by an inverted channel iron affords an absolutely water-proof joint. The purpose of the air chamber in the roof of the car is to insulate the interior of the car from exterior temperature. It has been found, in loading a car with commodities such as wheat or grain, that the cargo is often-times of such a temperature when sequent spoilingof part ofthe cargo. Es-

pecially is this the case when a car having a single roof, filled with grain, enters a tunnel where the atmosphere is damp and the temperature much lower than outside of the tunnel. With the insulated car roof,

such as I have described, this objectionable feature is eliminated, as the car roof, being insulated by the air chamber, will retain the temperature within the car, or at least cause the change'of temperature to be gradual, so that the temperature of the inside of the car gradually adjusts itself to the temperature outside of the car and thereby precipitation of the moisture is prevented. The chamber between the two roofs, which serves as an insulating medium, may be packed with asbestos or some other nonccnductor of heat, giving practically the same result as the air chamber.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do notwishto be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
